If you're interested in disrupting healthcare the founder of The Surgery Center of Oklahoma has a blog on pricing transparency. http://surgerycenterofoklahoma.tumblr.com/
Some additional resources:
Free Market Medical Association website. http://marketmedicine.org/members/ It lists all the resources and providers that provide transparent pricing.
The Pricing Healthcare Blog and Pricing Healthcare website is a crowd sourcing project where patients can input their medical bills and get the cash price of procedures in their area. (The CEO of Safeway started a company with Safeway's similar, proprietary, data, however they only sell the pricing data to companies with ~10,000+ employees).
The Self Pay Patient is a blog and resource for those that choose to self insure: http://selfpaypatient.com/
